WSJ report on Robert Kennedy Jr's efforts to remove artificial dyes in cereals used by Kellogg, General Mills, that are harmful to health and wellbeing of children and adults. RFK Jr is the nominee for Secretary Health and Human Services. Cereal made in Canada for Fruit Loops uses natural ingredients juice from carrots, water melon and blueberries to get the same colors. In the US artificial dyes are still used. When General Mills stopped using artificial dyes in Trix it changed the color and tasted bland according to food scientists in the company, leading to consumers not supporting the change. Large cereal companies are not taking the action needed when it comes to educating the public about the need for the change and making changes for healthy cereals.

The situation in farms and orchards in the U.S. as growers face shortages of labor to pick vegetable and fruit produce. A special visa program provides U.S. farms for vegetable and fruit produce with agricultural workers from Mexico. In 2019 this program brought in about 268,000 agricultural workers from Mexico.This report looks at the effort of companies to ensure that agricultural workers are well taken care of. This includes delivery of groceries to limit trips to nearby towns, offering food trucks with prepared meals. Problems of overcrowded housing and lack of access to health care are problems that are being tackled. Some companies are reconfiguring field work for health safety, and funding overtime work at local health clinics.

This excellent article by Peta Bee looks at how we can do anti-ageing efforts to keep our immune systems strong as we become older. She looks at work by an expert in immune cell biology, Janet Lord, who is head of the Institute for Inflammation and Ageing at Birmingham University. It is now proven that the link between ageing and immune systems can be guided in constructive ways. At sixty and seventy years age one can have the immune system of a 30 year old by doing a couple of simple things which are covered here from taking 10,000 steps a day, high intensity interval training on some days each month, occasional fasting on some days, high fibre diet and vitamin D. Walking, running or other forms of exercize affect a particular form of immune function called neutrophil movement in positive ways. Neutrophil movement because these cells are the main defense against the forms of bacteria that cause pneumonia. Neutrophils in older adults behaved in ways similar to that found in 30 year olds when doing 10,000 steps a day of exercize. Dr. Lord and other researchers have found. Dr. Jenna Macciochi, a lecturer in immunology at the University of Sussex, says about 70% of our immune system resides in our gut, making gut health very important for our immunity. Macciochi is the author of Immunity: The Science of Staying Well. Important for gut or gastrointestinal health is the eating of food that has prebiotic and probiotic effect. This helps reverse the decline of immunity coming with ageing.When we chew down on fibre in vegetables, fruit, beans or lentils we have beneficial byproducts called postbiotics that act as an interface between diet and immunity, that change the personalities of cells and circulate in our blood for regulation of immune system, says Dr. Macciochi. Postbiotics from eating dietary fibre tune up specific virus fighting cells that help us fight infections from flu and viruses, studies show says this report in The Times. Women in the UK get only 17g per day, men 20 mg per day of fibre. We need 30 mg per day of fibre and to do this we need to increase our intake of vegetables, fruits, whole grains, nuts, seeds and pulses. Also important is avoiding the inflammation that comes with ageing called inflammageing, says Dr. Macciochi. To do this do resistance training, weights, or using body weight such as lunges, push ups, squats. When our muscles move we produce hormones called myokines that help our immune cells function and keep inflammation down. She believes strength work is an absolute essential to rejuvenate our immune age. ...

Scientist Kim Mishra at the Swiss Federal Institute of Technology has come up with a method to make chocolate not just from the cocoa seeds discarding the pulp, husk and juice as is done today. This is wasteful. The new method uses the cocoa pulp, the husk and the juice as a way to make chocolate without sugar and use the whole fruit. This will reduce the impact on the climate with more chocolate production and less deforestation for new cocoa planted in South American countries as an addition to production in African countries like Ghana. It will also benefit cocoa farmers in Africa and Guatemala by increasing their income. This report looks at the colonial past of chocolate production by companies such as Lindt as Swiss producers worked with French and British colonies to expand production in the late 19th century.

The Federal Trade Commission says food companies in the U.S. spent $2.3 billion in 2006 for advertising to children. With the epidemic in childhood obesity in the U.S., this raises serious questions about how product packaging, images and themes affect the eating behaviour of children. New guidelines have now been written at the request of Congress. They were written by the F.T.C., the Food and Drug Administration, the Agriculture Department, and the Centers for Disease Control. The regulatory agencies say they will take comments and consider changes before submitting a report to Congress. The guidelines call for foods advertised to children to include healthy ingredients such as whole grains, fresh fruits and vegetables, or low fat milk. The foods cannot contain unhealthy amounts of sugar, saturated fat, trans fat and salt. The sugar requirement would have cereals contain no more than 8 grams of added sugar per serving. Fruit Loops for example contains 12 grams of sugar per serving. The guidelines apply to both children and teenagers. However these guidelines are voluntary. At this time an industry led effort has not produced results. The Children's Food and Beverage Advertising Initiative, which is operated by the industry, lets each company set its own nutritional criteria. The regulatory agencies see the need for the food industry to follow a uniform set of standards. Without serious action on this issue the U.S. healthcare system will continue to be burdened with high rates of obesity related illnesses in the general population, and out of control costs. And the U.S. will continue to face the urgent problem of a lack of healthy eating habits of children teenagers, and adults....

This essay from the Yale-Griffin Prevention Research Center which puts focus on preventive medicine looks at the food we eat in a different way. In order to have a real conversation on food it says ignore the latest fads on nutrition on keto, paleo or other diets, and think about how our ancestors ate in a healthy way that both prevented disease and provided the right nutrition. It was mostly plants as meat was not freely and easily available. So much so that the consumption of meat and animal protein may have gone up by as much as 90% today. Processed foods did not exist, and unprocessed plant foods were there in abundance. They were not called low fat low carb or vegan then. It is during the beginning of the 19th and in the 20th century that the production and marketing of shelf stable, nutrient poor, high calorie, high sugar and salt processed foods replaced the normal way our ancestors had their food leading to the public health crisis of today, both in health quality, outcomes and cost.  It says replace meat and where appropriate dairy healthier plant based beans, lentils, whole grains, and vegetables, fruits so that animal protein gets back to the levels of the centuries before the 20th century shift to processed foods. It says use common sense beans including soyabeans and lentil beans replace meat wherever possible and oats with berries and nuts replace eggs. Vegetable and garbanzo beans salad replaces cheese and yogurt reducing the cheese or yogurt to very moderate levels. Focus on wholesome food and eat like our ancestors did and exercize then everything else will fall into place. ...
